About SMP Standard Motor Products supplies ignition, sensor and electrical components across the automotive and powersports markets, with V-twin parts covering switches, sensors and ignition hardware. The SMP Electronic MAP Sensor is a crucial fuel-management component for V-twin motorcycles, precisely controlling fuel delivery timing based on engine load and throttle position to optimize combustion efficiency. Why riders pick this OEM-equivalent calibration for accuracy Monitors engine load and throttle position Direct bolt-on replacement for easy install Optimizes fuel delivery and combustion Your bike's Manifold Absolute Pressure (MAP) sensor plays a critical role in how your EFI system manages fuel. By accurately measuring the pressure within the intake manifold, it helps the ECU determine engine load, allowing for precise adjustments to fuel injection and ignition timing. A failing MAP sensor can lead to poor engine performance, hesitation, and reduced fuel economy. This SMP sensor ensures your V-twin runs cleanly and powerfully.Accurate Fuel Management OEM-equivalent sensor calibration for precise readings Compact sealed housing protects against elements Direct bolt-on replacement for straightforward installation Optimizes combustion efficiency based on engine load Seamless Integration and PerformanceDesigned as a direct bolt-on replacement, the SMP Electronic MAP Sensor makes it easy to maintain your V-twin's fuel management system. Its OEM-equivalent calibration ensures that your bike's ECU receives accurate data without the need for additional tuning or reprogramming. Riders can expect restored engine responsiveness and efficiency, making this an essential component for keeping your Harley-Davidson or Indian Motorcycle performing at its best.
